請(qǐng)幫忙修改幾個(gè)英文句子,編輯說(shuō)這幾個(gè)句子有問(wèn)題,多謝了! 1 Now, non-volatile holographic storage to maintain the information for a long time in this photorefractive crystal. 2Recently, using two coherent recording beams in the presence of a sensitizing bean with good nonvolatile holographic storage was achieved in doubly doped Ce:Fe:LN crystals 3 The concentration of Mg2+ in the melt was changed form 0 to 3mol% (0,1,2 and 3mol%) 4 The unpolarized ultraviolet-visible (UV-Vis ) absorption and infrared transmittance (IR) spectra were measured to analyzed the defect structure of these crystals, ranging from300-900nm and 400-4000cm-1.respectively. 5 The effective UV-Vis and IR range fro later discussion were from 360-600nm and 3400 to 3560 cm-1. |

1 Now, non-volatile holographic storage to maintain information has been put into use for a long time in this photorefractive crystal. (該句沒(méi)有主謂語(yǔ),我加了has been put into use) 2Recently, the usage of (把using 改為the usage of)two coherent recording beams in the presence of a sensitizing bean(這里應(yīng)該是beam 吧) with good nonvolatile holographic storage was achieved in doubly doped Ce:Fe:LN crystals. 3 The concentration of Mg2+ in the melt changed from 0 to 3mol% (0,1,2 and 3mol%) (去掉was,另外你把 from 寫成form了) 4 The unpolarized ultraviolet-visible (UV-Vis ) absorption and infrared transmittance (IR) (前面兩個(gè)單詞的首字母縮略詞不是IR吧?這兩個(gè)的意思不一樣哦) spectra were measured to analyze (analyzed 去掉d) the defect structure of these crystals, ranging from300-900nm to 400-4000cm-1.respectively.(把a(bǔ)nd 改為to, range from...to...) 5.The effective UV-Vis and IR range in(將fro 改為in) later discussion were from 360-600nm and 3400 to 3560 cm-1. 就這幾個(gè)單獨(dú)的句子,又沒(méi)中文,有點(diǎn)難懂哦,我不是你這個(gè)專業(yè)的,只能看看語(yǔ)法什么的,也只能改這么多咯,不知道改的對(duì)不對(duì),如果有不對(duì)的地方請(qǐng)指正。我把改了的地方給你標(biāo)記出來(lái)了,因?yàn)橐郧皠e人也是這么要求的 |
